GEORGE A. AMSDEN, OF LITTLETN, MASSACHUSETTS, SSIGNOR TO THE LA'MSUNLAVSUN CONSLIDATED STORE SER''CE COMNYQ 0F BOSTON, MASSACHUSETTS, ACURPORATION OF NEX/V JERSEY.

oannnc'enninn .arrenerns T QU fr0/ront it may concern y Bo it known thatI, Grenen A. Aisnmr, Vf ALittleton, in the county of ltfiiddlesex andState of ldassachusctts, have invented certain new and usefulImprovements in Cable? "traverse the bends and pass the idlers andpulleys supporting the cable without danger of throwing the carriers outof engagement with the cable and without necessitating the changing ofthe position of the carrier.

ln the accompanying drawings is illustrated a construction embodying myinvention in which- Figure 1 is an elevation of a 90 degree bendcomprising the corner of a cable carrier apparatus and showing a carriertrav-v ersing the same. is an end view vof Fig. 1 showing the trackbroken awayl on line Q looking in the direction indicated by the arrow.Fig. 8 is an enlarged view of a portion of one of the idlers orsupporting pulleys showing the position of the cable and carrier whiletraversing the same. Fig. l is a sectional view through the center ofone of the idlers.

Like characters of reference refer to like parts throughout the severalviews.

A and B represent respectively the outgoing and in-going tracks uponwhich the carrier is adapted to travel. The tracks B at the bend aresupported by the corner brackets D in which is journaled the idler orsupporting pulley E which supports the iii-going portion of the drivingcable C. The tracks A are supported at the bend by the corner bracket Fin which is liournaled the supporting pulley or idler G which sup portsthe out-going portion of the driving cable C. The brackets D and F aresupported in relative positions by the bent rod or shaft H which forms afixed shaft upon which the idlers E and G rotate. The idlers areconstructed with a central peripheral flange J which divides the pulleyinto two separate grooves P and L, see Figs. 3 and ll, one of which thecable normally traverses.

Then a carrier is being transmitted by Specification of Letters Patent.

the cable and arrives at one of the turns or bends as shown in Fig. 1,the jawn1 N and l which comprise the spring clamp of the can rier, areengaged by the sides of the grooves Pand L respcctively, retaining thecable C within said clamp and causing the cable to ride upon theperipheral flange l which also prevents the cable from being thrown outof the grip of the clamp, see Fig. 3. After the carrier passes the idlers and rounds the bend, the cable drops back to its normal position ineither of the grooves P and L.

l do not limit myself to the construction herein. shown as theperipheral flange J may be dispensed with forming a single groove pulleyand leaving the wedging action of the jaws N and K within 'the groove ofthe pulley to enable the carrier to make the turn without dropping thecable.

Having thus described my invention and set forth a constructionembodying' the same what I claim as new and desire to secure by LettersPatent of the United States is:

1. in a cable carrier apparatus, a track or way, an actuating'cable fordriving carriers along said track or way, a carrier having a clampcomprising opposing aws one at least of which is resilient, said jawsadapted to be resilientlyy clipped onto said cable, pulleys forsupporting said cable, and means for momentarily locking the jaws ofsaid clamp to prevent the resilient opening thereof and consequentdisengagement of said cable therefrom when the carrier passes saidpulleys.

2. In a cable carrier aparatus, a track or way, a carrier adapted totravel on said track or way, a cable for driving said 'carrier, a.spring clamp comprising opposing jaws, one at least of which isresilient, lo-

:ated on said carrier and adapted to be clipped into engagement withsaid cable, and a pulley located at a bend and adapted to support saidcable, said pulley carrying a central peripheral 'liange thereon adaptedto hold said cable securely between the jaws of said clamp when saidcarrier is passing said bend.

3. Cable carriei` apparatus comprising a track, a carrier to travelthereon, a cable for driving said carrier, said carrier having means toengage said cable, a pulley about which said cable normally passes andaround which said carrier is drawn by said ealile, "and means,independent el the earrier and its cable engaging means, te directlyengage said Cable and aid in retaining itin place in said cable engagingmeans Wlien said cable is pulled away from the vsurface of said pulleyby the passage of said carrier tliereareund,

1l. Cable carrier apparatus Comprising a track, a carrier to traveldiei-een7 a ealale fer driving; said Carrier, said carrier having meanste engage said cable, a pulley aloeut .which said Cable normally passesand areund which said Carrier is drawn lay said cable, means, carried bysaid pulley :lf-e1 direeely engaging said cable and fer alsa eugagingthe ealole engaging means ei' said carrier, to retain said cable inplace i said ealile engaging' means when j@lie Cable is pulled away fromthe surface el the pulley ay the passage of the carrier tliereareund.

ln a cable carrier apparatus, a track er way7 a Carrier adapied'ktotravel en said track er Way, a ealole for driving saideari'ier, a springclamp comprising` opposing; jaws, one at leash ei" which is resilie' lglocated on said carrier and adapted te engage said Cable, and pulleys eridlers located at the bends in said Way and adapted te support saidcable, eaela of said pulleys er idlers carrying a Central peripheral'liange thereon adapted te lield said cable securely between the jawsoi: said clamp When said carrier is passing' said bends, each el: saidpulleys also being provided with Hang s to engage the jaws ol'Clieearrier and held ythem clamped on the Cable when said Carrier ispassing` around' a pulley.

6. Cable Carrier apparatus Comprising a track, a carrier to traveldiei-een a cable for driving` said carrier, said carrier having means toengage said cable, a pulley about which' said cable normally passes andaround Wliieli said carrier is drawn by said cable7 andmeans,'independent oi' the ear .rier and its cable engaging means, todirectly engage said Cable and aid in retaining it in place in saidcable engaging means when said ealile is pulled away irem the surface ef'said pulley by the passage of "Peer engage said Cable substantially attlie peint.

Where it is by said 'arip "alien said Carrier' is traversins' a laendvinsaid traelg and enacting means te engage at least a part ef said grip atsuela times, said last tive mentioned means adapted te prevent saidcable ifrem springing nul, eil said grip at said bend.

ln testimony whereof, l have signed my name te 'this applieaion in thepresence oi' tive subseril'iing Witnesses, this ltlrday oi Sept. 1912. f
